No. Turing equivalence is not enough.

Turing equivalence allows you to compute the same things, true, but it does not allow you to _do_ the same things. For instance if you take brainf*ck, well known to be turing complete, how do you get brainf*ck to do a syscall? You can't.

Besides the computational power you also need the "functional" power. In Unix this means that you need syscalls. If you have syscalls then you have it all. (Since I/O for instance translates into syscalls).

On a more theoretical note you might observe that the Turing machine has an "infinite tape". So any machine that is equivalent to a turing machine will have to have infinite storage capacity.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
